"2 Claims. (Cl. -1-'58'99-) My invention relates to new and useful improvements in gas burner apparatus, and is directed more particularly to the provision of a gas burner which is constructed and arranged for various uses and is characterized 'by a novel means directed to an improvement in the means for facilitating the easy installation df .a. unit into and/or removal from .a stove orflike item of equipment whereinsuchfburner apparatusmay be installed.

It is the principal object of my invention to provide a novel and improved construction of the type in which novel means is provided to make quick installation quite possible and to make the removal of the apparatus once installed equally as possible. All of this is accomplished bysuch construction as will eliminate the now present objectionable inconveniences experienced by repairmen who install or repair such apparatus and will permit operation and maintenance with a maximum amount of ease and a minimum degree of effort.

With the above primary object in view, it is another object of my invention'to provide a construction of the above described character which a is relatively simple and compact in accordance with the demands and desires ofmanu'facturers and purchasers alike and which is not only attractive in its appearanceand'practical in its value but also "reliable in its operation and thoroughly efiicient in its use.

It is a still further object to provide adevice which is constructed of relatively simple parts which are adapted to be readily assembled'and which when once assembled can be readi'ly'se'parated from each other to permit quick repairs and/or replacements.

A special feature of the invention is directed to the provision-of a means for supporting the burner apparatus relative to the floor or base plate of a combustion chamber.

This means is adaptedto hold the-apparatus in the desired fixed position so as to "permit an upward flow of air adjacent the burner'bar and to be of such configuration and design "as to permit'the easy positioning of the burnerapparatus thereinto and the easy withdrawal of the burner apparatus therefrom.

As is well known, apparatus of thetype .to which the invention relates is used in ranges and the like and fuel such as gas is emitted from outlets of the burner bar with which a certain amount of air is needed for the desired combustion.

an air passageway is essential in the construction.

In't'he present invention, advantage" is taken of this'vital .air passageway .and the construction therearound is so designed .as to "provide the unique supporting means for the burner apparatus which is the principal feature ofthepresent invention.

other prime objects of my invention include: first, the provision of a simplified construction and arrangement of a gas burner apparatus .and supporting means therefor which is strong, durable and compact in it structure .and is distinctive in its appearance; second, the attainmentof a higher degree of speed of construction and assembly of the device .dueto' its simplification in design and it unique composition of parts; third, the attainment of a flexibility of a capability of adjustment by which a large variety of work can "be produced by means of the same device; fourth, the achievement .of .aigreater ease in adjustment and repairs; fifth, the provision of an improvedlgas burner apparatus which may be made more economically and with fewer operations in the manufacture of its parts, as well as inthe assembly of the same, than prior devices known inithe art.

All'oi the above objects I accomplish by means of such structure and relative arrangement of parts thereof, as will fully appear by a perusal of the description below and by various specific features which will bethereinafter set forth.

To the'ab'ove cited and-other ends and'with the foregoing "and various other novel features and advantages and other objects of my invention as'will become more readily apparent as "the description proceeds, my invention consists in certain novel features of construction and in the combination and arrangement of parts as will be hereinaftermoreparticularly pointed outjin the claims hereunto annexed and more fully described and referred to in connection with the accompanying, drawings wherein:

Fig. 6 is a sectional elevational view of the burner-tube of my invention in one stage of its formation; and

Fig. 7..is a sectional elevational view of the .burner tube shownin Fig. 6 after same "hasbeen completely formed.

Inthe above mentioned drawingannexed'liereto "and forming a part "of this specificationpl have shown but one embodiment of my invention which is deemed preferable, but it is to be understood that changes and modifications may be made within the scope of the appended claims without departing from the spirit of the invention.

Referring now to the drawing more in detail, and referring more particularly to the preferred form of my invention selected for illustrative purposes, I have shown a burner tube represented by H) which extends laterally and horizontally from a support l2. The support I2 is hollow and is adapted for connection by a pipe l4 to a gas supply system.

A pilot l6 fixed to the support 12 is of the conventional design.

The burner tube It is closed at the end opposite to the support l2 in a manner subsequently to be referred to and the gas carried in the tube is emitted through a series of ports H along the upper side of member ID. These ports may be of any desired size and may be relatively arranged so as to suit various conditions and requirements, all as is well known in the art.

A strut 20 is provided which is disposed directly below the tube and is arranged at one of its ends for securement to the support l2, as shown in Fig. 2, by means of a bolt 2! or the like.

A plurality of relatively thin plates or fins 30 are provided and these have openings in their upper edges for engagement with the member l9, as best shown in Fig. 5. These plates depend downwardly from the member iii, as shown in Figs. 1 and 2. The plates 3% also have notches in the lower edges thereof for engagement with the member 20, as best shown in Fig. 5.

Thus, it will be appreciated that the plates 38 are held in spaced parallel relation as to each other and relative to the members Iii and 20 all as is well known and described in detail in a patent to Homer D. Dufault, issued on October 15, 1946, and numbered 2,409,421.

The base or lower plate of a combustion chamher is generally indicated by the numeral 46.

It comprises a plate having an elongated opening 42 therethrough through which the apparatus above described may be inserted and/or withdrawn as will presently be observed.

Longitudinally elongated L-shaped supporting members 44 are disposed on either side of the burner apparatus and adjacent thereto. The support members support the member 49. The members 48 and 44 are otherwise fixed to each other as by bolts 49 or the like.

The member 40 may be of one piece so as to have a centrally located opening 42 therein or it may comprise a pair of elongated members which are spaced so as to provide the opening therebetween and may incorporate end panels such as 50 and 52 at opposite ends thereof which may be welded to the members 40 so as to enclose completely the opening 42 thereby to provide the aforementioned central opening.

The end panels 58 and/or 52.may be of such configuration as to fit snugly around the burner apparatus disposed through the opening 42. For example, in Fig. 1, it will be observed that an opening 53 is provided in the member 52 which is of such shape and design as to fit around the supply end of the burner apparatus.

At the ends of the members 44 adjacent the member [2, an end plate 60 is provided which is disposed between the members 44. This end plate is generally U -shaped so as to provide a cut-out portion 62 through which the burner apparatus may extend. This cut-out portion includes a shoulder 62' upon which the member it may rest when the burner apparatus is positioned relative to a combustion chamber, all as is shown in Fig. 4. It also includes a notch 64 in which the member 20 may nest.

Bolts 48 permit securement of said end plate 66 to the member l2 in the well known manner.

The end plate 60 is welded or otherwise secured to the members 44 and 44.

At the opposite ends of the members 44 and end plate It is provided which is disposed between the members 44. This end plate is generally U-shaped so as to provide a cut-out portion and a shoulder '12 upon which the member 10 may rest when the burner apparatus is positioned relative to the combustion chamber.

The end plate is welded or otherwise secured to the members 44 and 44.

Intermediate the ends of the members 44, a strengthening member is provided between the members 44 so as to reinforce the same. This strengthening member is generally U-shaped although it will be understood that it may be of any reasonable shape so long as it functions to add rigidity to the members 44.

As a special feature of the invention, I provide at the free end or at the end of the burner bar it opposite from the member If), a closure H. In forming the end, the end portion I0 of the bar is of relatively less thickness so as to provide an internal annular shoulder on which the cap or closure rests. The outermost extremity of the end portion 5 B is rolled inwardly after the member H is seated so as to enclose the member ll within the burner bar by means of the headedover portion H!" of the bar itself.

It will thus be observed that by means of the standard or cradle just described means is provided for the support of the gas burner apparatus.

The invention may be embodied in other specific forms without departing from the essential characteristics thereof. Hence, the present embodiments are therefore to be considered in all respects merely as being illustrative and not as being restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all modifications and variations as fall within the meaning and purview and range of equivalency of the appended claims are therefore intended to be embraced therein.
